I was upset, by the way, to see that Luboš recommends “shoot your environmentalist today” as a way to celebrate Earth Day. If he took himself seriously, then he’d have to wipe out 90% of theoretical physics, including many of the people he admires the most.
The fact is, conservatives like Luboš are a minority in physics. It’s not because of any discrimination, or because conservatives aren’t as good at math as liberals are. Studies have revealed that the brainy people with conservative personalities tend to feel more attracted to careers in business or law rather than academia.
The job of upholding old traditions is one that naturally appeals to conservatives. The job of discovering new knowledge tends to appeal more to people with a liberal disposition.
I’ve come to believe that evolution made humans separate into liberals and conservatives for a reason. We liberals need the conservatives to hold us back from accepting too many new ideas before they can be proven to be good ones, just like the conservatives need us liberals to keep society from choking to death on old outdated tradition.
Global warming won’t be the last debate we ever have, but it’s a debate that I wish I didn’t feel so confident at winning. I love to ski. I hope the vast majority of practicing professional climate scientists are wrong. Unfortunately, I think they know what they’re doing. I think they’re right and I think we need to pay attention to them now, not later when conservatives finally see the light.
